SPRING-HINGE.

Specification of Letters Patent.

Patented d an. 28, 1913.

Application filed April 29, 1912. Serial No. 693,922.

To all whom it may concern:

Be it known that I, GEORGE N. BARoUs, a citizen of the United States,and a resident of Wabash, county of Wabash, and State of Indiana, haveinvented a certain useful Spring-Hinge; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings.

The object of this invention is to provide an improved spring hingeconstruction which is suitable particularly for removable doors and thelike so as to render the same readily removable and as readily put inplace.

One feature of this invention consists in a spring construction betweenthe two hinged members whereby a simple and very strong hinge isprocured, the ends of the spring being connected with the end plates ofthe hinge members so that the ends of the spring, when the hingedmembers are folded together, will pass the pivot center between the twohinge members and thus the spring will hold the hinge members in theirfolded position. This enables a door, for instance, to be held open aswell as closed by the spring.

Another feature of the invention consists in the means for securing oneof the hinge members removably to the door, casing or other object so asto obtain a very secure mounting of the hinge, the hinge member beingsecured at both its inner and outer edges.

Another feature of the invention consists in the means for detachablylocking the hinge to the plate of the door or other object. To that endthe hinge member is fastened flat on a plate, the central portion of theplate remaining uncovered by the hinge member and said uncovered portionhaving an opening through it and the hinge member having a lockingmember pivoted thereto in position to enter the opening when operated.This locking member also cooperates with the means for holding thehinged member to the plate, as will hereafter appear.

The nature of the invention will be understood from the accompanyingdrawings and the following description and claims:

In the drawings, Figure 1 is a perspective view of the inside of thehinge and plate in unfolded and locked position. Fig. 2 is an endelevation thereof. Fig. 3 is an end elevation showing the same folded.Fig. 4L 1s a perspective view of the plate. Fig. 5 is a perspective viewof the hinge member which is removably secured to the plate. Fig. 6 is asection on the line 6-6 of Fig. 4. Fig. "I is a section on the line 77of Fig. 5.

The hinge portion of the structure consists of the hinge members 10 and11 having triangular shaped ends 12 and 13, respectively, withoverlapping cars 14 from each end, and through said overlapping ears apivot pin 15 extends. The pivot 15 is peculiarly formed, being bentbetween its ends 1nto an ogee shape, that is, being doubly bent so as tohave a portion 16 intermediate the two bends thereof which extendssubstantially at a right angle to the main portion of the pivot. Thespring 17 is coiled about the part 16 of the pivot and the two arms 18and 19 of the spring overlap each other when they are coiled, and thenextend longitudinally of the pivot 15 and their ends project through thecorresponding end plates 12. and 13 on the hinge members. The ends ofthe spring pass through the two end plates at about the same points withrelation to each other and the pivot 15. Hence, as shown in Fig. 1, whenthe hinge is unfolded, the two ends of the spring are 011 the same sideof the pivot. However, when the members of the hinge are being folded tothe position shown in Fig. 3, the ends 12 and 13 thereof carry the endsof the spring arm 19 around and past the pivot and thus will tend tohold the members in their folded condition. This spring constructionenables very strong spring wire to be used and affords a very simple anddurable spring construction.

The hinge member 10 is provided with screw holes 20 whereby it may besecured in place. The other hinge member 11 is secured to a metal plate21 and said metal plate 21 has screw holes 22 whereby it is screwed tothe door or other object.

The means for removably securing the hinge member 11 to the plate 21will now be explained.

As shown in Fig. 5, the hinge member 11 has on its under side areversely turned flange or hook 23 adapted to pass beneath and engagethe slightly elevated portion 24 at the inner edge of the plate 21, asindicated in Fig. 4, and thus the two inner edges of said hinge memberand plate are held together. The outer edge of the plate 21 is alsoprovided with an outwardly and reversely curved flange 25 adapted toreceive and overlap the rearwardly bent portion 26 of the outer edges ofthe hinge member 11 and thus the outer edges of the hinge member 11 andplate 21 are held together after they are put in place. plate 21 hasalso outwardly extending end flanges 27 which extend by the ends of thehinge member 11 and prevent longitudinal adjustment of the two parts.

,The central and outer portion of the plate 21 is not covered by thehinge member 11 when the parts are put together and the uncoveredportion ofthe plate 21 has an opening 30 in it about midway of the endsof the plate in position to receive a camlike member 31, when operated,as shown in Fig. l. Said locking lever 31 is pivoted on a pin 32extending through an upturned earv 33 about midway between the ends ofthe V hinge member 11. When the locking lever is turned to a verticalposition, the parts are unlocked.

WVhile there is herein shown and de scribed a construction in which theouter edges of the member 11 are held by a return curved portion on theouter edge of the stationary or fixed plate 21 and the inner edges areheld together by a hooked portion. on the hinge plate projecting behindthe inner edge of the fixed plate, it is not desired to limit myinvention to this particular invention as this construction may bevaried in many ways without departing from the spirit of my invention.

I claim as my invention:

1. A pair of hinge members having end portions extending substantiallyat right Theangles therefrom, a pivot rod extending through said endportions at both ends of the hinge member and having an intermediateportion extending transversely of the main portion of the pivot rod, anda spring coiled around said transverse portion of the pivot rod with thetwo arms thereof extending through the respective end portions at oneend of the hinged members.

2. A pair of hinge members, a plate adapted to be secured to a doorcasing or the like, said plate having outwardly bent portions adjacentits vertical edges, rear- Wardly bent portions adjacent the verticaledges of one of said hinge members adapted to horizontallyengage saidbent portions on said plate upon opposite faces of said plate, and meansfor removably locking said hinge member on said plate.

3. A pair of hinge members, a plate adapted to be secured to a doorcasing or the like, said plate having an outwardly bent portion adjacentits inner edge and the outer edge bent and returned, a lip upon the rearside of the inner edge of one of said hinge members adapted to slidablyengage the outward bend in said plate, the outer edge of said hingemember adapted to be slidably engaged by the return bend in said plate,and a lever on one of said hinge members for removably locking saidhinge member on said plate.

In witness whereof, I have hereunto affixed my signature 1n the presenceof the witnesses herein named.
